If you want to duplicate a layer in your Table of Contents (TOC) while keeping the Symbology, but without creating a new shp-file, ussualy this can be done very simple.


In ArcGIS

In version 10.x

  • Click in the TOC on the layer you want to copy while holding CTRL.
  • Drag the layer inside the TOC to the location you want to place the copy.
  • Release your mouse button.
  • The duplicated layer is created. You can now change the Symbology of your duplicated layer.

In QGIS

In version 1.8

In this version this function is not directly implemented, so you have to add a layer a second time as a workaround.

  • Add the layer you want to duplicate a second time as you would add any new layer.
  • Right Click on the version of the layer you want to copy the symbology from and select 'Copy style'
  • Right Click on the version of the layer you want to copy the symbology to and select 'Paste style'
  • Now you have a duplicated layer.


In version 2.0

  • Select the layer you want to duplicate in your TOC.
  • Go to Layer - Duplicate Layer(s)
  • The duplicated layer is created. You can now change the Symbology of your duplicated layer.

In version 2.6

You can use the same method as in version 2.0, but there is an even easier way.

  • Right click on the layer you want to duplicate in your TOC.
  • select 'Duplicate'
